  2. Biodegradable

  3. Non-biodegradable

  4. All of the above

Show answer
Correct Option: B

Rag pickers remove

solid waste and its management conservation of environment

  1. plastic, polythene, paper and metal wastes

  2. rags, cardboard, glass articles

  3. both (a) and (b)

  4. food articles.

Show answer
Correct Option: C
Explanation:
Rag pickers remove recyclable materials from the wastes such as plastic, polyethene, paper, metal wastes, rags, cardboard, glass articles etc. because all these items can be recycled and reused. For example, the paper is recycled into a usable form, metals and plastic can be melted and recycled any number of times, glass articles are recycled to form new articles as the quality of glass is not affected on recycling. 
Food articles are biodegradable and hence, they are not recycled.
Hence, options A and B are correct.
So, the correct answer is 'both (a) and (b)'.

Explanation:

There are various steps which are involved in the safe management of the solid waste. Reduce, reuse, recycling, sorting, processing, recovery and disposal are major steps of integrated waste management. The important step before the last step is the energy recovery. The forms of wastes which can be recovered to obtain energy can be segregated and the remaining waste forms can be disposed. This reduces the energy which will be required for the transport and the final disposal of the waste.

Thus, the correct answer is option B.
